I have a website built with Python Flask (hosted on Heroku) and I am utilizing the js Wake Lock API to keep the user's device alive. Basically my site connects with the NHL's API and plays a goal horn when your team scores. I have added a Wake Lock toggle to the page where the app runs to allow users to enable the feature.
Here is my problem: I am being told Wake Lock is not compatible with the browser when I deployed to my production environment. Everything worked just fine locally when running in the same browser. Here is my Wake Lock code:
const checkbox = document.querySelector('#wakeLock');
const statusElem = document.querySelector('#wakeLockStatus')
const updateUI = (status = 'acquired') => {
const acquired = status === 'acquired' ? true : false;
checkbox.dataset.status = acquired ? 'on' : 'off';
checkbox.checked = acquired ? true : false;
statusElem.textContent = `Wake Lock ${acquired ? 'is active!' : 'is off.'}`;
}
// test support
let isSupported = false;
if ('wakeLock' in navigator) {
isSupported = true;
statusElem.textContent = 'Wake lock API is supported in your browser!';
} else {
checkbox.disabled = true;
statusElem.textContent = 'Wake lock is not supported by this browser.';
}
if (isSupported ) {
// create a reference for the wake lock
let wakeLock = null;
// create an async function to request a wake lock
const requestWakeLock = async () => {
try {
wakeLock = await navigator.wakeLock.request('screen');
// change up our interface to reflect wake lock active
updateUI()
// listen for our release event
wakeLock.onrelease = function(ev) {
console.log(ev);
}
wakeLock.addEventListener('release', () => {
// if wake lock is released alter the button accordingly
updateUI('released');
});
console.log(wakeLock)
} catch (err) {
// if wake lock request fails - usually system related, such as battery
checkbox.checked = false;
statusElem.textContent = `${err.name}, ${err.message}`;
}
} // requestWakeLock()
// toggle
checkbox.addEventListener('click', () => {
// if wakelock is off request it
if (checkbox.dataset.status === 'off') {
requestWakeLock()
} else { // if it's on release it
wakeLock.release()
.then(() => {
wakeLock = null;
})
}
})
}
Like I said, this was working perfectly when testing locally, but when I deployed it no longer works. It is this part that is failing because I see the "Wake Lock is not supported in this browser" message on the front end. The app is hosts on Heroku, if that matters.
// test support
let isSupported = false;
if ('wakeLock' in navigator) {
isSupported = true;
statusElem.textContent = 'Wake lock API is supported in your browser!';
} else {
checkbox.disabled = true;
statusElem.textContent = 'Wake lock is not supported by this browser.';
}

Thank you in advance for any help!!
I found the solution. Wake Lock requires HTTPS and I was just using an HTTP connection as I was still using the free Heroku plan. I have upgraded and it is working as expected.
